just made myself an elites usb passthrough . not too difficult although the positive lead is very thin and if it breaks would be nearly impossible to replace. now produces a decent amount of vapour at 1 amp and 5 volts. i do have another one at 1.5 amps and 5 volts but it seems to scorch the juice a bit and almost too much vapour. any way way better than a standard elites and at least its better than tossing the elites. to be honest i do not see how anybody could quit smoking using one of these things. just not enough vapour. loads at 5 volts though.
